Babies typically travel free on airplanes until they are under two years old.
According to information gathered on January 25, 2024, airlines generally allow babies under the age of two to fly for free, although taxes may still apply. It's important to note that these infants do not get their own seat and must sit on the lap of an adult. Furthermore, airlines usually restrict one child per adult for this arrangement. So, while someone might refer to their four or five-year-old as a "toddler," this free flight policy specifically applies to babies under two years old.
